Specification forming part of Letters Patent No. 18,341, dated June 20, 1865.

-To all whom it may concern:

art to make and use the same, reference being bad to the accompanying drawings, forming part of this specification; in which- Figure lrepresents a vertical central section of this invention, the line as m, Fig. 2, indicating the plane of section. Fig. 2 is a horizontal section of the same. the line 3 y, Fig. 1, indicating the plane of section. 7

Similar letters of reference indicate like parts.

This invention relates to a bottle-stopper composed of a plug of wood or other suitable material perforated through its longitudinal center, in combination with a .conevalve eecnred to a stem which passes through the hole in the plug, and with an elastic tubeapplied to the outside of said plug in such a manner that when the plug, with the elastic tube, is inserted in the neck of a bottle containing liquid under pressure the pressure of the gases in the liquid forces the cone-valve up into the elastic tube and expands the same, causing it to close tight against the inner surface of the neck.

A represents a plug, of wood or any other suitable material, which is perforated-through its longitudinal center with a hole, a. Through this hole passes the stem b of a cone-valve, B,

and a weak spring, 0, has a tendency to raise this cone-valve up, or to sustain it in the position shown in Fig. 1 of the drawings.

Secured to the outside of the plug A is a tube, of indie-rubber or other suitable elastic material, just thick enough to pass freely into the neck of a bottle. If the stopper is introduced intothe neck. of a bottle filled with gaseous liquids the pressure of the gases'i'orces the cone-valve up into the tube, causing the same to expand and to form a tight joint against theinner surface of. the neck. A slight pressure on the top of the stem b forces the cone-valve out of the elastic tube, and allows of withdrawing the stopper from the bottle without difficulty.

'If desired, the plug A and tube 0 can be made solid out of india-rubber,\although I use, bypreference, a wooden plug and an indie-rubbertnbe. The valve is best made of tin or-- other material which is not injured or touched by the liquid or gases with which it may come in contact.

I claim as new and desire to secure by Letters Patent- A bottle-stopper composed of a plug, A

tially as herein set forth.
